    Hi, running a System76 Lemur 3 with an i7 sandybridge. Latest 12.10 kernel 3.5.0-26 been getting this message:

    in my syslog for weeks. Thought it was related to an apport issue, but have now disabled apport and issue is still there. It begins at boot up and repeatedly occurs every 2-5 mins, even when laptop is idle.


    Any ideas?

    I have seen reports like this before, but have not seen a good solution.
